Abstract: A lighting device (1) for a vehicle headlamp is provided. The lighting device includes an illuminant (2), a collimator (4), a mirror device (5) with a reflection surface (5a), and a DMD device (6). The mirror device (5) is arranged downstream of the collimator (4), wherein the reflection surface (5a) of the mirror device (5) is configured to reflect a first part of the light from the illuminant and to transmit a second part of the light from the illuminant. The mirror device (5) is configured in such a way that the reflected part is free of UV light and the transmitted part has UV light. The DMD device (6) is configured to modulate and deflect the first part of the light from the illuminant.

Abstract: A hydropneumatic suspension system arranged on a bogie for a vehicle, particularly for a rail vehicle, and one hydropneumatic suspension unit respectively which is contained in the suspension system. For this purpose, the spring accumulator, the reservoir, the tank and the control unit are arranged in the area of the at least one spring strut, so that an essentially self-sufficient suspension unit is obtained. The suspension system may be used and connected to a levelling unit.

Abstract: The present invention is a process and system for controlling the wagon body of a vehicle which can be used alone or in combination with a steel spring system. The control system has comparatively small geometrical dimensions and requires relatively little energy and includes a pressure accumulator connected in parallel to delivery pump 8 of the hydraulic pressure medium. The two devices working together against the pressure of the hydropneumatic pressure accumulator of the body height system. Thus, the pressure accumulator can be charged during the travel of the vehicle so that the pump does not have to be designed according to the peak load in the case of a fast load change.

Abstract: The invention relates to a sway brace on rail vehicles. The aim of the invention is to find a solution in which the effort and expense needed to produce the sprung sway braces can be reduced and the transverse forces and the resultant wear occurring on deflection can be reduced to the minimum. This is achieved by the invention in that one end of the sprung sway braces in a special design is arranged in a support with defined guide surfaces while the other end is secured to the piston of a hydraulic cylinder via an axial rocker beating. In addition, there is a disc spring column above the sway brace.
